First Thoughts on the CMB GBL-STPR XT MOS 20
The CMB GBL-STPR XT MOS 20. Even the name suggests a no-nonsense, purpose-built tool. I’ve been working with shotguns for over a decade, from upland bird hunting to tactical applications, and I’m always intrigued by specialized chokes, especially those geared toward turkey hunting. The CMB GBL-STPR XT MOS 20, with its designation as a turkey choke and its black finish, immediately piqued my interest.
My primary goal was to find a reliable, consistent choke that could deliver tight patterns at longer ranges for turkey hunting. Standard chokes often leave gaps in the pattern, reducing the effective range. My quest was for precision and lethality.
The CMB GBL-STPR XT MOS 20 came in simple, functional packaging. The black finish looked durable, and the choke itself felt substantial. Compared to some of the more aggressively ported chokes I’ve used, the CMB GBL-STPR XT MOS 20 had a clean, straightforward design. I own a Carlson’s Long Beard XR choke, which is similar in function but with a ported design, and a Briley extended choke for general field use. The CMB GBL-STPR XT MOS 20 seemed to strike a balance between the two.
I was cautiously optimistic. A $28.99 choke isn’t going to boast the fancy finishes or intricate designs of some of the higher-end options. But if it delivers on pattern density and consistency, then the CMB GBL-STPR XT MOS 20 will be a winner.
Real-World Testing: Putting CMB GBL-STPR XT MOS 20 to the Test
First Use Experience
I tested the CMB GBL-STPR XT MOS 20 at my local shooting range, focusing on pattern density at 30 and 40 yards. I primarily used Winchester Long Beard XR shells, as they are known for their tight patterns. The weather was clear and mild, around 60 degrees Fahrenheit with a light breeze.
The initial results were impressive. The CMB GBL-STPR XT MOS 20 produced a noticeably tighter pattern compared to my standard modified choke, with significantly fewer gaps. I was pleasantly surprised by the consistency, with each shot grouping predictably.
There were no immediate issues. The CMB GBL-STPR XT MOS 20 threaded smoothly into my Mossberg 500, and there were no signs of loosening after several shots.
Extended Use & Reliability
After several weeks of use and approximately 50 rounds through the CMB GBL-STPR XT MOS 20, it’s holding up remarkably well. The black finish shows no signs of wear, despite repeated installation and removal for cleaning. Cleaning the choke is straightforward; a simple bore brush and solvent easily remove any residue.
I have found the CMB GBL-STPR XT MOS 20 to be more consistent than some of the cheaper, unbranded turkey chokes I’ve used in the past. Those often produced inconsistent patterns or even became damaged after limited use. The CMB GBL-STPR XT MOS 20 offers significantly improved performance and durability for the price.
Breaking Down the Features of CMB GBL-STPR XT MOS 20
Specifications
- Gauge: 20 Gauge. This is a crucial specification, as it determines the compatibility with your shotgun.
- Choke size: Turkey. Designed specifically for tight patterns at longer ranges, ideal for turkey hunting.
- Finish: Black. A durable finish that protects against corrosion and wear.
These specifications are vital for turkey hunting. A 20-gauge shotgun is often preferred for its reduced recoil and manageable weight, especially for younger or smaller-framed hunters. A turkey choke is essential for achieving the dense patterns needed to ethically harvest a turkey at reasonable distances.
Performance & Functionality
The CMB GBL-STPR XT MOS 20 performs admirably in its intended role. It consistently delivers tight, dense patterns, increasing the effective range of my 20-gauge. The pattern density at 40 yards is particularly impressive, providing confidence in making ethical shots.
The primary weakness is that it’s a specialized choke. It’s not ideal for close-range shooting or for use with shot types other than those recommended for turkey hunting (typically lead or heavier-than-lead shot). It excels at its specific purpose, but its versatility is limited. The CMB GBL-STPR XT MOS 20 meets expectations and even exceeds them for its price point.
Design & Ergonomics
The build quality is surprisingly good for a choke in this price range. The materials feel solid, and the black finish is evenly applied. It’s a simple, functional design with no unnecessary frills.
The CMB GBL-STPR XT MOS 20 is easy to install and remove with a standard choke wrench. There is no learning curve; it functions like any other screw-in choke.
Durability & Maintenance
Based on my experience so far, the CMB GBL-STPR XT MOS 20 should last for many seasons with proper care. Regular cleaning after each use will help prevent corrosion and maintain consistent performance. The simple design makes it easy to inspect for any signs of damage.
Accessories and Customization Options
The CMB GBL-STPR XT MOS 20 does not come with any accessories. However, it’s compatible with any standard 20-gauge choke wrench. There are no specific customization options for the choke itself, but it can be paired with various optics or sights on your shotgun to further enhance accuracy.
